EMM (electromagnetic mill)-promoted Pd-catalyzed solid state intramolecular Heck-type cyclization/boronation and Suzuki couplings are reported. Compared to previous mechanochemistry that constructed one chemical bond through a cross-coupling reaction, this strategy realizes cascade transformation along with multiple chemical bond formation. This conversion does not require organic solvents or additional heating, and it shows a good substrate scope and high functional group tolerance.

EMM 促进的 Pd 催化固态分子内 Heck 型环化/硼化和 Suzuki 偶联：获得功能化二氢吲哚

报道了 EMM（电磁磨）促进的 Pd 催化固态分子内 Heck 型环化/硼化和 Suzuki 偶联。与之前通过交叉偶联反应构建一个化学键的机械化学相比，该策略实现了级联转变以及多个化学键的形成。这种转化不需要有机溶剂或额外的加热，并且表现出良好的底物范围和高官能团耐受性。
